Screensaver doesn't work on KDE 3.5

[Joseph Vella]

Since upgrading to 3.5 the screensaver won't come on by itself.  It runs 
from the control panel when you hit test, it runs when you lock session, it 
just won't do it by itself.

Has anyone figured out this problem yet?  I know it's not just me because in 
all my searching I find others that have the same issue.
This problem exists for me on three machines with KDE 3.5. (two have been 
upgraded to 3.5.1, still same problem)
